Michael was recommended to me by a retired Forensic Document Examiner I had used previously who had since retired. I have since used Michael for expert, Forensic Document Examination and Handwriting Comparison work for High Court proceedings. I found Michael to be very thorough and his expert report presented in an easy-to understand manner. It was also turned around very quickly when needed”

I spent three years searching for a Forensic Expert in Ireland and many other countries. They all replied, but were afraid to tackle the corruption at the highest level of our society in Ireland. Michael Moore stepped up to the challenge. His work is independently fearless, professional, accurate and in my case a game changer. I sincerely thank Michael for his professional ability and independence”
